NSAIDs such as aspirin block platelet function by causing a reversible defect in the enzyme cyclooxygenase. Unlike aspirin which permanently acetylates cyclooxygenase and leaves affected platelets dysfunctional throughout their 7-day life span, NSAIDs cause a reversible defect that lasts 3 to 4 days. Therefore, the patient's platelets will be functional for surgery if he stops taking the NSAIDs 3 to 4 days prior to the date of surgery. The patient would not benefit from FFP or vitamin K since he does not have problems with his clotting factors.
